    Can you help me with this...many thanks

  • grayanne Feb 10, 2008

    hi c-dog. i can't find a reset feature in the menu the only reset button i can find is the reset button on picture adjust section. i tried unpluging the wall outlet but still the problem exist, actually i can only view the menus while im turning off the lights and trying to sit very close on the tv, that way i can see a little shadows of the words, basically a black pop-up onscreen on display still showing when pressing any feature button on the remote.

  • grayanne Feb 11, 2008

    sorry im not a technician.

    by the way, on the black pop-up onscreen display whenever i press the feature buttons, when i stand close to the tv and turn off the lights i could see some shadowing of the words but very very minimal visibility and its so hard to read

  • grayanne Mar 01, 2008

    i was thinking too that its a convergence problem, because when im turning on the tv there's a green shadowing on the left side, but when you start watching programs you wont see that green shadows.

    can you just tell me how to fix that convergence problem, i really dont know how, or do i need a qualified technician to do that, or i can do it too?

In your customer menu there is a convergence adjustment feature. just follow the instructions on how to do it. It's pretty simple. But if that doesn't do it, then you may have some components shorted or open in the convergence circuit. If so, then you will need a qualified tech to repair it.

I'm not entirely sure, but I think the problem lies in your Convergence OSD PWB. I had to disconnect mine in the attempt to troubleshoot a problem with my TV and the same thing occurred. I would check your connection from your Convergence PWB to your Convergence OSD PWB; especially if you recently recently changed your IC's to fix a color convergence problem. If that checks out ok I would look for possible problems on the Convergence OSD PWB. Good luck!

    Try and see if there is some sort of a reset feature in the menu. Also try to unplug the set from the wall outlet for a few minutes then plug it back in. That resets the microprocessor from being stuck in a loop of some kind.

    When the internal temperature gets high then the photo coupler efficiency decreases. This would sometimes result in the menu display freezing up not being able to see any of the PTV functions. Are you a technician?

Cant turn off closed caption


With our VIP receiver models, you have an option to turn on/off closed caption through the receiver. Press the Menu button on the remote, which will display the Main Menu on the TV screen. Press 8 (Preferences) and then press 6 (Closed Caption). On the Closed Caption screen, press 1. On the Closed Caption On/Off screen, select CC Off and then press Done from the TV screen (using your DISH remote). This will turn the feature off on the receiver. Test to see if it is turned off by watching a program that has CC. If it still appears, then the feature is activated through your TV. Please refer to your TV manual to turn the feature off. I hope this helps.

Black boxes in the middle of the screen are text boxes. Text is a part of the closed captioning feature either on your television or your cable/set top box. You would press the closed captioning button on the remote repeatedly until it displays cc off or something similar. Captioning might also be active on your cable box/set top box. There is normally a hidden menu on the cable box and that is where closed captioning is. You have to turn the cable box off. Yes I did say turn the cable box off. Then press the menu button on it and then the hidden menu will pop up. Then navigate to closed captioning and choose disable.
